[IC-7000] 80m problem

Simon Thompson All Messages By This Member #34979 开云体育 RF is getting in to radio. Try to route coaxial cables away from other power or microphone cables, or any other cable that might provide an inductive path for rf energy to reenter radio. The same thing happened to me. toggle quoted message Show quoted text On Dec 14, 2013, at 1:42 AM, simonesbressa@... wrote: ? hi guys , i have a strange problem in 80m when push ptt full or about middle pwr the radio change band automatically?for example 20m or change operative mode , practically goes crazy, only in 80m?this happens?, the swr is about 3 or more , the mic is original , the antenna is single harm like bb6 un un 9:1, the power supply 30 amp, when i utilize about 30w or less all is ok.....

Dave Schmidt #34980 With an SWR of 3:1 or greater ... I can see why the 7K is acting funky. RF is getting into the radio. Ground the radio with a flat braid or flat copper strap and fix the antenna. The 7K is not going to be happy with that SWR, it will be folding back RF power as well as heating up the unit. toggle quoted message Show quoted text On Sat, Dec 14, 2013 at 3:24 PM, Simon Thompson <simonthompson67@...> wrote: ?
